Malbolge has three registers, a, c, and d. When a program starts, the value of all three registers is zero. a stands for 'accumulator', set to the value written by all write operations on memory and used for standard I/O. c, the code pointer, is special: it points to the current instruction. d is the data pointer. It is automatically ...
C ( pronounced / ˈsiː / – like the letter c) [6] is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted CPUs. It has found lasting use in operating systems code (especially in kernels [7 ...

The C Programming Language (sometimes termed K&R, after its authors' initials) is a computer programming book written by Brian Kernighan and Dennis Ritchie, the latter of whom originally designed and implemented the C programming language, as well as co-designed the Unix operating system with which development of the language was closely intertwined.
Code.org. Code.org is a non-profit organization and educational website founded by Hadi and Ali Partovi [1] aimed at K-12 students that specializes in computer science. [2] The website includes free coding lessons and other resources. The initiative also targets schools in an attempt to encourage them to include more computer science classes in ...
In the C programming language, an escape sequence is specially delimited text in a character or string literal that represents one or more other characters to the compiler. It allows a programmer to specify characters that are otherwise difficult or impossible to specify in a literal. An escape sequence starts with a backslash ( \) called the ...
Object lifecycle[edit] In class-based programming, an object is created as an instance of a class; is a class instance. A client creates an object via a constructor, and destroys the object via a destructor. An abstract class cannot be instantiated. In prototype-based programming, instantiation involves copying (cloning) a prototype instance.
